Abstract: The present application discloses methods and apparatuses for tag management. In an example method, a first mobility management function receives a registration request message sent by an access network device. The registration request message requests to register a tag in a core network. The first mobility management function obtains identification information of a second mobility management function from a unified data management function based on the registration request message. The second mobility management function stores context information of the tag. The first mobility management function obtains the context information of the tag from the second mobility management function.

Abstract: A communication method and apparatus are provided, to support data transmission over a multi-access session through multiple 3GPP paths or multiple non-3GPP paths. Access technologies corresponding to a first transmission path and a second transmission path in the multi-access session are of a same access type. A session management device sends, to a mobility management device, tunnel information and access technology information that correspond to the transmission paths, where the access technology is used to determine an access network device. The mobility management device determines the access network device based on the access technology information, and sends the tunnel information to the access network device. In this application, the session management device sends, to the mobility management device, the access technology information which is a finer granularity than an access type, and the mobility management device can accurately identify a corresponding access network device based on the access technology information.

Abstract: Embodiments of this application disclose a packet transmission method and a related apparatus. An access network device receives a first packet from an Internet-of-things (IoT) function network element; the access network device obtains first information, where the first information indicates that the first packet includes a passive or semi-active IoT instruction; and the access network device performs a passive or semi-active IoT operation based on the first packet. According to the foregoing method, the access network device learns that the packet from the IoT function network element is related to a passive or semi-active internet of things, and the access network device performs the passive or semi-active IoT operation based on the first packet. This resolves a packet transmission problem in a scenario in which a passive or semi-active IoT system is converged with a cellular network.

Abstract: This application provides a communication method and apparatus, to provide a non-3GPP path switching solution in a multi-access session. The method includes: A session management device determines to perform non-3GPP transmission path switching in a multi-access session, where the multi-access session includes at least two non-3GPP transmission paths; and the session management device sends a first offloading rule to a user plane device, where the first offloading rule is for supporting the user plane device in determining a first target transmission path from at least two non-3GPP transmission paths. According to the method, when it is determined to perform non-3GPP path switching, UE and a UPF can select, in a switching process based on a new offloading rule, an appropriate path from a plurality of non-3GPP access paths for data transmission, to ensure service continuity during session switching.

Abstract: Embodiments of this application provide a terminal management method and a core network device. The method includes: A first core network device receives a first message from a terminal. When determining, based on quantity information, to allow the terminal to access the network, the first core network device sends a second message to an operation requester to which the terminal belongs. The quantity information includes a quantity of terminals that the operation requester is allowed to use, the second message includes first identification information. In embodiments of this application, the first core network device determines to allow the terminal to access the network, so that a quantity of terminals accessing the network among terminals corresponding to the operation requester can be prevented from being greater than or equal to the quantity of terminals that the operation requester is allowed to use.
